Honestly, if you're a light user who doesn't use Google Chrome, you're probably good with the MBA.
Why is the MBA not suitable for Google Chrome?
It is suitable, but Safari is much more efficient. Chrome is a pig and tends to hurt Air performance
I totally get the appeal of a MacBook Air with a U series processor and a butterfly keyboard.Both computers are great! I tend to prefer the Air because of its sloped body and no Touch Bar. Granted it's slower and has a slightly dimmer screen than the Pro, but most people won't notice that in daily use.
